SWINGTNG WINZDOW-SASE-I.

Specification of Letters Patent.

Patented Got. 27, 1914;.

Application filed. December 22, 1912. Serial no. 808,071.

To all whom it may concern Be it known that T, WVILLIAM BAYLEY, a citizen of the .United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Swinging Winlow-Sashes, of which the following is a specification.

My invention relates to swinging window sashes and particularly to means for pivotally supporting such sashes at points intermediate theirv extremities.

lVin'dow sashes for use in factories, auditoriums or public buildings are frequently constructed in units of great length, in some cases approximating several hundreds of feet. Such sashes as commonly constructed, are too heavy to be supported upon trunnions located only at the extreme ends.

The present invention is designed to afford means for pivotally supporting such a window sash at various points throughout its length, whereby it may be swung about such pivotal connection as a single unit.

The object of the invention is to simplify the structure as well as the means and mode of operation of such swinging sashes, whereby they will not only be cheapened in construction, but will be more efficient in use, capable of being easily and quickly operated and unlikely to get out of alinement or repair.

Referring to the drawings, Figure 1 is a vertical sectional view of a metallic window sash, showing the medial support therefor, which forms the subject matter hereof. Fig.

2 is a front elevation of a window sash,"

showing one of the end trunnions and one of the medial supports. Fig. 3 is an enlarged detail vertical sectional view of the medial pivotal connection. Fig. 4 is a similar sectional view upon line as-m of Fig. 3. 5 is a transverse sectional plan view of the connection. Fig- 6 is a detail perspective view of the bearing block. Figs. 7 and 8 are detail side elevation and front elevation respectively of a modification of the construction shown in the preceding figures. Fig. 9 is a detail view showing the use of the channel iron in lieu of the I beam shown in the preceding figures. Figs. 10, 11, 12 and 13 illustrate further modifications of the construction shown in the previous figures.

Like parts are indicated by similar characters of reference throughout the several views.

In the drawings, 1 is the cap bar and 2 the sill bar of the window opening. In this case both cap and sill bars are shown as angle irons. While the swinging sash may be of any suitable construction, it has been shown in the drawings as a metallic sash and having transversely arranged sash bars 3 upon. which are supportedthe glass 4. The margins of the sash are provided with angle irons 5, which abut upon the cap and sill bars 1 and 2 and uponthe vertical frame bars 6 at the sides of the window opening when the sash is in its closed position; The sash is connected with the vertical frame bars 6 at each side of the window opening by trunnions 7 of any suitable construction.

As thus far described, the construction does not differ from that commonly employed in swinging metallic window sashes.

Located at intervals throughout the window opening are vertical struts or posts 8 connected by brackets 10 with the cap and sill bars 1 and 2. Each of the vertical struts 8 is offset as at 9 at a point in alinement with the axis of oscillation of the shaft. The construction is such that the upper portion of each strut will be upon one side of the sash, and the lower portionthereof will be located upon the opposite side of the sash, while the transverse connecting or offset portion 9 extends through the sash. To permit the strut or post 8 to pass through he sash without interfering with the swinging movement thereof, the vertical sash bars 3 are arranged in pairs one upon each side of each strut or post as is shown in Fig. 2.

It will be understood that the vertical sash bars 3 are so arranged only at points coincident with struts or supports and that intermediate the supports or struts, single sash bars are employed in the usual manner. In Figs. 1 to 5 of the drawings, the supports or struts 8 have been shown in the form of I beams. It is obvious that rectangular bars may be employed or that channel irons as shown in Fig. 9 may be substituted for the I beams.

The vertical sash bars 3 are spacedapart a distance only suflicient to permit the strut or support to pass between them. The strut or support is pr'o'videdwith t hole or apes.-

ing in axial alinement with the trunnion 7 at ends of the sash. As shown in the drawing, such pivotal Opening is located in the transverse or offset portion of the strut. Located in the channel of the I beam on opposite sides of the support or strut, are

filler blocks 10 extending flush with the 013 posite faces of the beam. The filler blocks are secured in place by riveting as indicated 1o at 11. Each filler block is provided with a hole registering with that of the strut or support. Secured to the parallel sash bars '3 and located intermediate the webs thereof,

is a recessed bearing block 13 through which 15 the transverse portion of the strut with the attached filler blocks 10 projects. The bearing block 18 is likewise provided with an opening 14:, registering with the corresponding openings of the filler blocks and strut.

20 A trunnion or stud 15 passes through the registered openings of the bearing block, the

filler blocks and the strut as shown in Fig 4:. Thebearing blocks 13 being secured to the parallel sash bars by means of rivets or by bolts as shown in Fig. 4-, will oscillate in unison with the sash about its pivotal connection with the strut or support formed by the trunnion stud 15. It is to be under stoodthat this trunnion stud 15 is an axial alinement with the trunnions 7 at the oppo- Lsite ends of the sash.

In assembling .the structure, the filler blocks 10 are placed in position on opposite .sides.of the strut to fill the channels thereof. The bearing block 13 is then passed overthe end of the strut which passes through the (recess .ofthe block until theopening 14: is brought into registry with the correspond- ..ing' opening ofthefiller block and struts, whereupon the trunnion stud15is inserted. The. trunnion stud 15 is of such length as to extend substantially flush with the faces of the bearing block- 13. .The sash ,is then placed in position and secured to the bear ing block by means ofrivets or by the bolts asindicated iii-Fig. 4:. It will be noted that thewebs of the parallel sash bars 3 extend- .ing on opposite sides of the bearing block 13, prevent the. escape of the trunnion stud 15. --The sash will thenbe free to swing upon thetrunnions 7; at its extremities. and the medial trunnionstuds 15, which are distributed atintervals throughoutits length. The narrow slot or openingin the sash intel-mediate the parallel sash bars 3, above and .below the offset of the strut or post are closed by. narrow strips 16 of metal, glass or other material secured therein by cement or other means. ina manner similar-to the manner. of securing -the;glass 4. In theevent that a channel beam is employed. in. lieu of thewI beam previouslydescribed, a single ffillerblock 12 will beemployed as shown in .Fig. ,9. Otherwise, .the construction ,is the ,same I as previously described.

7 In Figs. 7 and 8 there is shown a modification of the construction in which there is employed a strut or post formed from angle irons 17 arranged in pairs, each memberof the pair being in reversed position and the pairs being offset one with the other, whereby one pair of angle irons will be on one side of the sash and the other pair upon the op-- posite side of the sash, the adjacent ends of the two pairsof the angle irons being connected by a coupling plate 18, which is interposed between the individual angle irons of each pair. I In this case the vertical frame sash bars 3-8 will be separated one from the other a distance equal'to the thickness of the coupling plate 18.

The construction and operation of. the sash is similar to that previously described. Any suitable means may be provided for adjusting the sash or maintaining it inits ad justed position.

ln Fig. 10thereis. shown a modification somewhat similar tothat disclosed inFigs. 7 and 8 but differing therefromirithat the uprights or struts'19 may be single members, either bars,

posed plate 20 in lieu of the verticalppl ate 18 in the previous construction. -ln this construction the'sash. is provided with two parallel centrally disposed sashkbars 3'3 arranged one-upon each side of the axis of 0s,

cillation. This provides an intermediate space 21 through which the transverse connecting plate 20 projects. The. iopening channels or I beams and are. connected by a transverse horizontally dis above and bclow'the plate-20=is closed by flexible flanges 22 secured tothe sashba-rs 3 upon each side of the plate and bearing at their free edges upon the plate '20. ;These flanges 22 areadapted to yield as; the sashis oscillated and by their resiliency, maintain a constant engagement with the transverse connecting plate 20.

In Fig. 11 there is shown a-modification employing a straight upright'or -strut23 and an. offset sash, the sections 24 of which are connected by. a transversehorizontally disposed ,plate 25. -The plate 25 is providedwith suit able (perforations ,or ppenings through which the :upright orastrut 23; projects. In. this construction one .section: 24: :of

the sash is located at the innersi-de-otthe upright or strut 23,.while. the other-section is located at the -outer .;side; of the strut. This construction permitsthe sash-to be oscillatedas inditated by idotted; lines without interfering with the. strut or support.

' The; particular form ofswingingsasheand supporting strut .herein sh own described .lends itself readilyto the applicationvof' fly screens. 3 It. has heretofore been: the; custom when applying fly screens toiswing ing. sashes to form the screen into a; semi cylindrical form -or chamber within which the swinging sash may oscillate. By the present construction the screen may be adjusted parallel with the normal position of the sash and permanently secured in position. Thus the fly screen will occupy no more space and will not differ in appearance from the screen constructed as ordinarily employed with sliding windows.

In Fig. 10 screen sections 26-26 are shown supported upon the strut sections 19, where they are secured by angle bars or other means as indicated at 27. It is to be noted that the screen is divided into two sections one section being located upon the outer side of the sash and the other section upon the inner side of the sash. By this construction the sash in its oscillatory movement will move to and from the respective sections. The space intermediate the adj acent edges of the screen sections is effectually closed by the spring flanges 22. The application of screen sections to the construction shown in Fig. 11 is quite similar to that of Fig. 10. The screen sections 26 aresecured to the opposite sides of the upright or strut 23.

In Fig. 11, yielding spring flanges 28 are shown supported upon the upright or struts F38 and bearing at their free edges upon the transverse connecting plate 25 by which the sash sections 24. are connected one with the other. These spring flanges by maintaining their contact with the plate 25 at all times close the opening between the respective sections of the sash and the screen.

In Figs. 12 and 18 there is shown constructions quite similar to that disclosed in Figs. 1 to 5. Two different methods of applying screens to such constructions are shown in these figures. In Fig. 12, screen sections 29 are stationarily secured to the opposite sides of the offset studs or supports. These screen sections 29 each have a flexible section 30 at their adjacent edges, which section is secured to the swinging sash. As the sash is oscillated about its pivotal connection, the flexible section 30 will yield as indicated by dotted lines to permit the ready movement of the sash while effectually closing the window opening against the entrance of insects. It will be noted in this figure that one portion of the screen section is secured to the strut or support while the other portion is secured to the sash.

In Fig. 13 is shown a construction somewhat similar in which the screen sections 31 are secured at their outer or extreme edges to the strut or support or if desired may be secured direct to the window casing, while at their inner or adjacent edges the screen sections 31 are attached to opposite sides of the swinging sash. The screen sections 31 being flexible permit the ready adjustment of the sash the screen sections assuming positions as indicated by dotted lines in said figure.

From the above description it will be apparent thatthere is provided a device of the character described, possessing the particular features of advantage before enumerated as desirable, but which is obviously susceptible of modification in its form, proportion, detail construction or arrangement of parts, without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute, the invention has been described in language more or less specific as .to certain structural features, it is to be understood that the invention is not limited to any specific details, but that the means and construction herein described comprise but one mode of putting the invention into effect, and the invention is therefore claimed broadly in any of its possible forms or modifications within the scope of the appended claims.

Having thus described my invention, I claim:

1. A swinging sash, supporting struts therefor extending through the sash at points coincident with the axis of oscillation, and pivotal connections between the sash and the struts.

2. A swinging sash having openings therein coincident with the axis of oscillation, supports therefor projecting through said openings and pivotal trunnions connecting the sash and supports.

3. A window sash swinging on a medial axis of oscillation and a plurality of separated pivotal trunnions therefor arrange in spaced relation intermediate the ends of the sash and coincident with the axis of oscillation, and a strut extending through the sash and supporting the said trunnions.

4. A swinging sash having medially disposed trunnions at its opposite ends, a strut passing through the sash intermediate its ends and an intermediate trunnion carried by the strut, separated from, but alined with the end trunnions.
